START-UP OVERVIEW The following procedure is an overview of the minimum steps necessary for bringing an ATV31 drive controller into service. Refer to the ATV31 Installation Manual for the mounting, wiring, and bus voltage measurement steps. Refer to the appropriate sections of this manual for the programming steps.
1. Mount the drive controller. Refer to the ATV31 Installation Manual.
2. Make the following connections to the drive controller. Refer to the ATV31 Installation Manual:
— Connect the grounding conductors.
— Connect the line supply. Ensure that it is within the voltage range of the drive controller.
— Connect the motor. Ensure that its rating corresponds to the drive controller’s voltage.
3. Power up the drive controller, but do not give a run command.
4. Configure bFr (motor nominal frequency) if it is other than 50 Hz. bFr appears on the display the first time the drive controller is powered up. It can be accessed in the drC- menu (page 27) anytime.
5. Configure the parameters in the drC- menu if the factory configuration is not suitable. Refer to page 10 for the factory settings.
6. Configure the parameters in the I-O-, CtL-, and FUn- menus if the factory configuration is not suitable. Refer to page 10 for the factory settings.
7. Configure the following parameters in the SEt- menu (pages 23–27):
— ACC (acceleration) and dEC (deceleration)
— LSP (low speed when the reference is zero) and HSP (high speed when the reference is at its maximum)
— ItH (motor thermal protection)
8. Remove power from the drive controller and follow the bus voltage measurement procedure in the ATV31 Installation Manual. Then connect the control wiring to the logic and analog inputs.
9. Power up the drive controller, then issue a run command via the logic input (refer to the ATV31 Start-Up Guide).
10. Adjust the speed reference.
Section 1: Introduction VVDED303042USR6/04Preliminary Recommendations 06/2004

PRELIMINARY RECOMMENDATIONS
Precautions Before powering up and configuring the drive controller, read and observe the following precautions.
DANGERUNINTENDED EQUIPMENT OPERATION
• Before powering up and configuring the drive controller, ensure that the logic inputs are switched off (State 0) to prevent unintended starting.
• An input assigned to the run command may cause the motor to start immediately upon exiting the configuration menus.
Failure to follow these instructions will result in death or serious injury.
WARNINGLOSS OF CONTROL
• The designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure.
• Examples of critical control functions are Emergency Stop and Overtravel Stop.
• Separate or redundant control paths must be provided for critical control functions.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
CAUTIONDAMAGED EQUIPMENT
Do not operate or install any drive controller that appears damaged.
Failure to follow this instruction can result in equipment damage.
VVDED303042USR6/04 Section 1: Introduction06/2004 Preliminary Recommendations
© 2004 Schneider Electric All Rights Reserved 9
Starting from Line Power If you are starting the drive controller from line power, ensure that parameter tCt is not set to trn (see page 31) and limit operations of the line contactor to fewer than one per minute to avoid premature failure of the filter capacitors and precharge resistors. The recommended method of control is through inputs LI1 to LI6. The motor thermal state memory returns to zero when line power is removed from the drive controller.
Power Up after a Manual Fault Reset or Stop Command
If parameter tCt is at its factory setting (trn), when the drive controller is powered up after a manual fault reset or a stop command, the forward, reverse, and DC injection stop commands must be reset for the drive controller to start. If they are not reset, the drive controller will display nSt and will not start. If automatic restart is configured (parameter Atr in the FLt- menu, see page 77) the reset is not necessary.
Test on a Low Power Motor or without a Motor
With the factory configuration, motor phase loss detection (OPL) is active. To check the drive controller in a test or maintenance environment without having to switch to a motor with the same rating as the drive controller, disable motor phase loss detection and configure the voltage/frequency ratio (UFt) to L, constant torque (see page 29). The drive controller will not provide motor thermal protection if the motor current is less than 0.2 times the nominal drive current.
Using Motors in Parallel When using motors in parallel, configure the voltage/frequency ratio, UFt, to L (constant torque) and provide an alternate means of thermal protection on every motor. The drive controller cannot provide adequate motor thermal protection for each motor.
Operation on an Impedance Grounded System
When using the drive controller on a system with an isolated or impedance grounded neutral, use a permanent insulation monitor compatible with non-linear loads.
ATV31••••••M21 and N4 drive controllers feature built-in radio frequency interference (RFI) filters which have capacitors to ground. These filters can be disconnected from ground when using the drive controller on an impedance grounded system to increase the operating life of their capacitors. Refer to the ATV31 Installation Manual for more information.
Programming Recommendations Refer to “Start-Up Overview” on page 7 for the minimum programming steps necessary for bringing the drive controller into service.
Use the configuration settings tables beginning on page 89 to prepare and record the drive configuration before programming the drive controller. It is always possible to return to the factory settings by setting the FCS parameter to InI in the drC-, I-O-, CtL-, or FUn- menus. See pages 30, 33, 47, and 75.
When first commissioning an ATV31 drive controller for a 60 Hz system, perform a factory parameter reset. Be sure to set bFr to 60 Hz.
We recommend using the auto-tuning function to optimize the drive controller’s accuracy and response time. Auto-tuning measures the stator resistance of the motor to optimize the control algorithms. See page 29.
1 Throughout this manual, the symbol “•” in a catalog number denotes the portion of the number that varies with the drive controller rating.

VVDED303042USR6/04 Section 1: Introduction06/2004 Drive Thermal Protection
© 2004 Schneider Electric All Rights Reserved 11
DRIVE THERMAL PROTECTION Thermal protection of the drive controller is achieved with a positive temperature coefficient (PTC) resistor on the heatsink or power module. In the event of an overcurrent, the drive controller trips to protect itself against overloads. Typical tripping points are:
• Motor current is 185% of nominal drive controller current for 2 seconds
• Motor current is 150% of nominal drive controller current for 60 seconds
Ventilation The fan starts when the drive controller is powered up, but stops after 10 seconds if a run command is not received. The fan starts automatically when the drive controller receives an operating direction and reference. It stops a few seconds after motor speed is less than 0.2 Hz and injection braking is completed.

MOTOR THERMAL PROTECTION Motor thermal protection is achieved by continuous calculation of heat energy (I2t). The protection is available for self-cooled motors.
NOTE: The motor thermal state memory returns to zero when line power is removed from the drive controller.
Refer to “Preliminary Recommendations” on pages 8–9 for more information about external overload protection.
CAUTIONINADEQUATE MOTOR THERMAL PROTECTION
The use of external overload protection is required under the following conditions:
• Starting from line power
• Running multiple motors
• Running motors rated at less than 0.2 times the nominal drive current
• Using motor switching

• Pressing or does not store the selection.
• To store the selection, press the key.The display flashes when a value is stored.
A normal display with no fault present and no run command shows:
• The value of one of the display parameters (see page 82). The default display is motor frequency, for example 43.0. In current limiting mode, the display flashes.
• init: Initialization sequence
• rdY: Drive ready
• dcb: DC injection braking in progress
• nSt: Freewheel stop. See the following section.
• FSt: Fast stop
• tUn: Auto-tuning in progress
If a fault is present, the display flashes.
nSt: Freewheel Stop If the display shows the code nSt, one of the following conditions is indicated:
1. With the factory configuration, when the drive controller is powered up after a manual fault reset or stop command, the forward, reverse, and DC injection stop commands must be reset for the drive controller to start. If they are not reset, the drive controller will display nSt and will not start. If automatic restart is configured, the reset is not necessary.
2. If the reference channel or the control channel is assigned to Modbus or CANopen (see page 34), the drive controller will display nSt on power up and remain stopped until the communication bus sends a command.
3. If a forward or reverse run command is present when the drive controller is powered up and the drive controller is set for 3-wire control or for 2-wire control with “trn” transition (see page 31), the drive controller will display nSt and will not run until the run command is cycled and a valid speed reference is given.

REMOTE KEYPAD DISPLAY The optional remote keypad display is a local control unit that can be wall-mounted on the door of an enclosure. It has a cable with connectors for connection to the drive serial link (refer to the manual supplied with the display). The remote keypad display has the same display and programming buttons as the drive controller, with the addition of a switch to lock access to the menu and three buttons for commanding the drive controller:
• FWD/REV commands the direction of rotation.
• RUN commands the motor to run.
• STOP/RESET commands the motor to stop or resets a fault. Pressing the STOP/RESET button once stops the motor; pressing it a second time stops DC injection braking if it is configured.
In order for the remote keypad display to be active, the tbr parameter in the COM- menu must remain at the factory setting, 19.2 (19,200 bps, see page 80).
NOTE: Password protection has priority over the access locking switch. See page 84.
Placing the access locking switch in the locked position also prevents the drive settings from being accessed via the drive controller keypad. When the remote keypad display is disconnected, if the access locking switch is in the locked position, the drive controller keypad also remains locked.
Saving and Loading Configurations Up to four complete configurations can be stored in the remote keypad display and transferred to other drive controllers of the same rating. Four different operations for the same device can also be stored on the terminal. See the SCS and FCS parameters in the drC-, I-O-, CtL-, or FUn- menus. See pages 30, 33, 47, and 75.

VVDED303042USR6/04 Section 2: Programming06/2004 Function Compatibility
© 2004 Schneider Electric All Rights Reserved 19
FUNCTION COMPATIBILITY Automatic restart, catch on the fly, and reverse direction are only available as described below:
• Automatic restart is only available in 2-wire control (tCC = 2C and tCt = LEL or PFO, see page 31).
• Catch on the fly is only available in 2-wire control (tCC = 2C and tCt = LEL or PFO, see page 31). It is deactivated if automatic DC injection braking is configured as DC (AdC = Ct, see page 53).
• Reverse direction is only available on ATV31••••••A controllers if local control is active (tCC = LOC, see page 31).
The choice of application functions is limited by the number of I/O available and by the fact that some functions are incompatible with one another as illustrated in the figure below. Functions which are not listed in the figure are fully compatible. If there is an incompatibility between functions, the first function configured will prevent the others from being configured.
Stop functions have priority over run commands. Speed references via logic command have priority over analog references.

The parameters in the SEt- menu can be modified with the drive controller running or stopped. However, we recommend making modifications to the settings with the drive controller stopped.
DANGERUNINTENDED EQUIPMENT OPERATION
Ensure that changes to the operating settings do not present any danger, especially when making adjustments while the drive controller is running the motor.
Failure to follow these instructions will result in death or serious injury.
CAUTIONMOTOR OVERHEATING
• This drive controller does not provide direct thermal protection for the motor.
• Use of a thermal sensor in the motor may be required for protection at all speeds or loading conditions.
• Consult the motor manufacturer for the thermal capability of the motor when operated over the desired speed range.
Failure to follow these instructions can result in equipment damage.

UFr
IR compensation or voltage boost 0 to 100% 20
If UFt (page 29) = n or nLd, UFr is IR compensation.If UFt = L or P, UFr is voltage boost.
Used to optimize torque at very low speed. Increase UFr if the torque is insufficient.To avoid operating instability, ensure that the value of UFr is not too high for a warm motor.
NOTE: Modifying UFt (page 29) will cause UFr to return to the factory setting (20%).
FLG
Frequency loop gain 1 to 100% 20
This parameter can only be accessed if UFt (page 29) = n or nLd.
FLG adjusts the speed ramp based on the inertia of the driven load.If the value is too low, the response time is longer. If the value is too high, operating instability can result.
StA
Frequency loop stability 1 to 100% 20
This parameter can only be accessed if UFt (page 29) = n or nLd.
After a period of acceleration or deceleration, StA adapts the return to a steady state to the dynamics of the machine.If the value is too low, overspeed or operating instability can result. If the value is too high, the response time is longer.
SLP
Slip compensation 0 to 150% 100
This parameter can only be accessed if UFt (page 29) = n or nLd.
SLP adjusts slip compensation for fine tuning of speed regulation.If the slip setting < actual slip, the motor is not rotating at the correct speed in steady state.If the slip setting > actual slip, the motor is overcompensated and the speed is unstable.

rSC
Cold state stator resistance See below. nO
nO: Function inactive. For applications that do not require high performance or do not tolerate automatic auto-tuning (passing a current through the motor) each time the drive is powered up.
InIt: Activates the function. Used to improve low-speed performance, whatever the thermal state of the motor.
XXXX: Value of cold state stator resistance used, in mΩ.
NOTE: We recommended that you activate this function for lifting and handling applications. This function should only be activated when the motor is cold.
When rSC = InIt, parameter tUn is forced to POn. At the next run command, the stator resistance is measured with an auto-tune. The value of parameter rSC then changes to this measured stator resistance value (XXXX) and is maintained at that value; tUn remains forced to POn. Parameter rSC remains at InIt as long as the stator resistance measurement has not been performed.
Value XXXX can be forced or modified using the keys.
tUn
Motor control auto-tuning See below. nO
Before performing an auto-tune, ensure that all the drive control parameters (UnS, FrS, nCr, nSP, COS) are configured correctly. Parameter tUn can be modified with the drive controller running; however, an auto-tune will only be performed if no run or braking command is present.
nO: Auto-tuning is not performed.YES: Auto-tuning is performed as soon as possible, then the parameter automatically switches to dOnE or, in the event of a fault, to nO. The tnF fault is displayed if tnL = YES (see page 79).dOnE: Auto-tuning is completed and the measured stator resistance will be used to control the motor.rUn: Auto-tuning is performed each time a run command is sent.POn: Auto-tuning is performed each time the controller is powered up.LI1 to LI6: Auto-tuning is performed when the logic input assigned to this function transitions from 0 to 1.
Note:
tUn is forced to POn if rSC is any value other than nO.
Auto-tuning will only be performed if no run or braking command is present. If a freewheel stop or fast stop function is assigned to a logic input, this input must be set to 1 (active at 0). Auto-tuning may last for 1 to 2 seconds. Wait for the display to change to dOnE or nO. Interrupting auto-tuning may result in an auto-tuning fault (see page 86) and cause the motor to be improperly tuned. During auto-tuning, the motor operates at nominal current.
tUS
Auto-tuning status(status information only, cannot be modified) See below. tAb
tAb: The default stator resistance value is used to control the motor.PEnd: Auto-tuning has been requested but not yet performed.PrOG: Auto-tuning is in progress.FAIL: Auto-tuning has failed.dOnE: Auto-tuning is complete. The stator resistance measured by the auto-tuning function is used to control the motor.Strd: Auto-tuning is complete. The cold state stator resistance is used to control the motor (rSC must be other than nO).
UFt
Selection of the voltage/frequency ratio See below. n
L: Constant torque (for motors connected in parallel or special motors)P: Variable torque (pump and fan applications)n: Sensorless flux vector control (for constant torque applications)nLd: Energy savings (for variable torque applications not requiring high dynamics.

Switching frequency1 2.0 to 16 kHz 4 kHz
Adjust this setting to reduce audible motor noise. If the switching frequency is set to a value higher than 4 kHz, in the event of excessive temperature rise, the drive controller automatically reduces the switching frequency. It increases it again when the temperature returns to normal. If switching frequency is set above the factory setting (4 kHz), refer to the ATV31 Installation Manual for derating curves.

The factory setting is 60 Hz, or 72 Hz if bFr is set to 60 Hz.

Suppression of the speed loop filter See below. nO
nO: The speed loop filter is active (prevents the reference from being exceeded).YES: The speed loop filter is suppressed. In position control applications, this setting reduces the response time, but the reference may be exceeded.
SCS
Saving the configuration2 See below. nO
nO: Function inactiveStrI: Saves the current configuration (but not the result of auto-tuning) to EEPROM. SCS automatically switches to nO as soon as the save is performed. Use this function to keep another configuration in reserve, in addition to the current configuration.
The drive controller is factory set with the current configuration and the backup configuration both initialized to the factory configuration.
If the remote keypad display is connected to the drive controller, up to four additional settings are available: FIL1, FIL2, FIL3, and FIL4. Use these selections to save up to four configurations in the remote keypad display’s EEPROM memory. SCS automatically switches to nO as soon as the save is performed.
FCS
Return to factory settings/Restore configuration2 See below. nO
nO: Function inactiverECI: Replaces the current configuration with the backup configuration previously saved by SCS (SCS set to Strl). rECI is visible only if the backup configuration has been saved. FCS automatically changes to nO as soon as this action is performed.InI: Replaces the current configuration with the factory settings. FCS automatically switches to nO as soon as this action is performed.
If the remote keypad display is connected to the drive controller, up to four additional selections are available corresponding to backup files loaded in the remote keypad display's EEPROM memory: FIL1, FIL2, FIL3, and FIL4. These selections replace the current configuration with the corresponding backup configuration in the remote keypad display. FCS automatically changes to nO as soon as this action is performed.
Note: If nAd briefly appears on the display once the parameter has switched to nO, the configuration transfer is not possible and has not been performed (because the controller ratings are different, for example). If ntr briefly appears on the display once the parameter has switched to nO, a configuration transfer error has occurred and the factory settings must be restored using InI. In both cases, check the configuration to be transferred before trying again.
NOTE: For rECI, InI, and FIL1 to FIL4 to take effect, you must press and hold down the ENT key for 2 s.1 This parameter can also be accessed in the Settings menu, SEt-. See page 23.2 SCS and FCS can be accessed in several configuration menus, but their settings affect all menus and parameters as a whole.

SCS
Saving the configuration1 nO
nO: Function inactiveStrI: Saves the current configuration (but not the result of auto-tuning) to EEPROM. SCS automatically switches to nO as soon as the save is performed. Use this function to keep another configuration in reserve, in addition to the current configuration.
The drive controller is factory set with the current configuration and the backup configuration both initialized to the factory configuration.
If the remote keypad display is connected to the drive controller, up to four additional settings are available: FIL1, FIL2, FIL3, and FIL4. Use these selections to save up to four configurations in the remote keypad display’s EEPROM memory. SCS automatically switches to nO as soon as the save is performed.
FCS
Return to factory settings/restore configuration1 nO
nO: Function inactiverECI: Replaces the current configuration with the backup configuration previously saved by SCS (SCS set to Strl). rECI is visible only if the backup configuration has been saved. FCS automatically changes to nO as soon as this action is performed.InI: Replaces the current configuration with the factory settings. FCS automatically switches to nO as soon as this action is performed.
If the remote keypad display is connected to the drive controller, up to four additional selections are available corresponding to backup files loaded in the remote keypad display's EEPROM memory: FIL1, FIL2, FIL3, and FIL4. These selections replace the current configuration with the corresponding backup configuration in the remote keypad display. FCS automatically changes to nO as soon as this action is performed.
Note: If nAd briefly appears on the display once the parameter has switched to nO, the configuration transfer is not possible and has not been performed (because the controller ratings are different, for example). If ntr briefly appears on the display once the parameter has switched to nO, a configuration transfer error has occurred and the factory settings must be restored using InI. In both cases, check the configuration to be transferred before trying again.
NOTE: For rECI, InI, and FIL1 to FIL4 to take effect, you must press and hold down the ENT key for 2 s.1 SCS and FCS can be accessed in several configuration menus, but their settings affect all menus and parameters as a whole.

CONTROL MENU CTL-
Control parameters can only be modified when the drive controller is stopped and no run command is present. This menu can be accessed with the access locking switch on the remote keypad display in the position.
Control Channels Control commands, such as forward and reverse, and speed reference commands can be sent to the drive controller from the sources specified in Table 6. ATV31 drive controllers allow you to assign control and reference sources to separate control channels (Fr1, Fr2, Cd1, or Cd2, see pages 44–45) and to switch between them. For example, you might assign LCC to reference channel 1 and CAn to reference channel 2 and switch between the two reference sources. It is also possible to use separate sources for control and reference commands. This is called mixed mode operation. These functions are explained in detail in the sections beginning on page 36.

Parameter LAC Use parameter LAC (page 44) in the CtL- menu to select levels of function access and to set the control and reference sources.
1. LAC = L1: Level 1—access to standard functions. Control and reference commands come from one source. See “Parameter LAC = L1 or L2” on page 36.
2. LAC = L2: Level 2—access to all of the level 1 functions, plus the advanced functions listed below. Control and reference commands come from one source. See “Parameter LAC = L1 or L2” on page 36.
— +/- Speed (motorized potentiometer)
— Brake control
— Switching for 2nd current limit
— Motor switching
— Management of limit switches
3. LAC = L3: Level 3—access to all of the level 2 functions. Control and reference commands can come from separate sources. See “Parameter LAC = L3” on page 37.
Section 3: Menus VVDED303042USR6/04Control Menu CtL- 06/2004
© 2004 Schneider Electric All Rights Reserved36
Parameter LAC = L1 or L2 If parameter LAC is set to L1 or L2, the control and reference commands come from one source. The possible control and reference sources, and the settings that specify them, are:
• Control and reference via the input terminals or the drive keypad display in forced local (see FLO on page 80)
• Control and reference via the Modbus serial link
• Control and reference via the CANopen serial link
• Control and reference via the remote keypad display (see LCC on page 46)
NOTE: Modbus or CANopen is selected online by writing the appropriate control word (refer to the protocol-specific documentation).
The diagram below illustrates the order of priority when more than one control and reference source is specified. In the diagram, information flows from left to right. At step 1, LCC is not set to YES to enable the remote keypad display, so the drive keypad display is selected as the control and reference source. At steps 2–4, Modbus, CANopen, and forced local control are not set to YES, so the drive keypad display remains the selected source. The order of priority, therefore, is forced local, CANopen, Modbus, and the drive keypad display or the remote keypad display. For example, if forced local mode were enabled, it would have priority over any other setting. Similarly, if CANopen were enabled, it would have priority over any other setting except for FLO. Refer to the diagrams on pages 39 and 40 for more detail.
• On ATV31•••••• drive controllers with the factory configuration, control and reference commands come from the control terminals.
• On ATV31••••••A drive controllers with the factory configuration, control commands come from the drive keypad display and reference commands come from a summation of the reference potentiometer and AI1 on the control terminals.
• With a remote keypad display, if LCC = YES (see page 46), control and reference commands come from the remote keypad display. The reference frequency is set by parameter LFr in the SEt- menu (see page 24).

Use these selections to save up to four configurations in the remote keypad display’s EEPROM memory. SCS automatically switches to nO as soon as the save is performed.
FCS
Return to factory settings/Restore configuration1 See below. See below.
nO: Function inactiverECI: Replaces the current configuration with the backup configuration previously saved by SCS (SCS set to Strl). rECI is visible only if the backup configuration has been saved. FCS automatically changes to nO as soon as this action is performed.InI: Replaces the current configuration with the factory settings. FCS automatically switches to nO as soon as this action is performed.
If the remote keypad display is connected to the drive controller, up to four additional selections are available corresponding to backup files loaded in the remote keypad display's EEPROM memory: FIL1, FIL2, FIL3, and FIL4. These selections replace the current configuration with the corresponding backup configuration in the remote keypad display. FCS automatically changes to nO as soon as this action is performed.
Note: If nAd briefly appears on the display once the parameter has switched to nO, the configuration transfer is not possible and has not been performed (because the controller ratings are different, for example). If ntr briefly appears on the display once the parameter has switched to nO, a configuration transfer error has occurred and the factory settings must be restored using InI. In both cases, check the configuration to be transferred before trying again.
NOTE: For rECI, InI, and FIL1 to FIL4 to take effect, you must press and hold down the ENT key for 2 s.1 SCS and FCS can be accessed in several configuration menus, but their settings affect all menus and parameters as a whole.

WARNINGDISABLED STOP COMMAND
Disabling the stop key on the drive keypad display or the remote keypad display will prevent the drive controller from stopping when the stop key is pressed. An external stop command must be installed to stop the motor.
Failure to follow this instruction can result in death, serious injury, or equipment damage.

APPLICATION FUNCTIONS MENU FUN-
Application function parameters can only be modified when the drive controller is stopped and with no run command present. On the remote keypad display, this menu can be accessed with the access locking switch in the position.
Some functions in this menu have numerous parameters. To simplify programming and to minimize scrolling, these functions are grouped into sub-menus. Like menus, sub-menus are identified by a dash. For example, LIA- is a sub-menu, but LIn is a parameter.
It is not possible to configure incompatible application functions. The first function configured will prevent any functions that are incompatible with it from being configured. Refer to the function compatibility table on page 19.

+/- Speed This function can only be accessed if:
1. Parameter LAC is set to L2 or L3 (see page 44).
2. Incompatible functions are not active (see page 19).
3. Parameter Fr1 or Fr2 is set to UPdt or UPdH.
The following sections describe two types of +/- speed operation: use of single action buttons and use of double action buttons. A pendant station is an example application of both.
Single Action Buttons Single action buttons require two logic inputs and two directions of rotation. The input assigned to the + speed command increases the speed, the input assigned to the - speed command decreases the speed.
Example of wiring:
LI1: forward LIx: reverseLIy: + speed (USP)LIz: - speed (DSP)
The maximum speed is set by HSP (see page 24).
NOTE: If the reference is switched via rFC (see page 45) from any reference channel to another with +/- speed, the value of reference rFr (after ramp) is copied at the same time. This prevents the speed from being incorrectly reset to zero when switching takes place.

Double Action Buttons Only one logic input, assigned to + speed, is required for double action buttons. Double action buttons typically have two detents. Press the button to the first detent to maintain speed; press it to the second detent to increase speed. Each action closes a contact. Refer to the following table.
Example of wiring:

PI Regulator PI regulator provides regulation of a process using feedback from a sensor that sends a signal to the drive controller. This function is often used for pump and fan applications. The PI regulator function is activated by assigning an analog input to PI regulator feedback (PIF).
The PI regulator feedback parameter (PIF, see page 66) must be assigned to one of the analog inputs (AI1, AI2, or AI3).
The PI reference can be assigned to the following parameters, in order of priority:
• Preset references via logic inputs (rP2, rP3, and rP4, see page 66)
• Internal reference (rPI, see page 67)
• Reference Fr1 (see page 44)
Refer to the following table for combining logic inputs for preset PI references.
The following parameters can also be accessed in the Settings menu (SEt-, beginning on page 23):
• Internal reference (rPI)
• Preset references (rP2, rP3, rP4)
• Regulator proportional gain (rPG)
• Regulator integral gain (rIG)
• PI feedback multiplication coefficient (FbS):
The FbS parameter can be used to scale the reference to the variation range of the PI feedback (sensor range).
For example, Pressure control:PI reference (process) = 0 to 5 bar = 0 to 100%Range of pressure sensor = 0 to 10 bar FbS = Maximum sensor scale / Maximum process FbS = 10 / 5 = 2

Can be used to set the PI error threshold above which the PI regulator is reactivated (wake-up) after a stop due to the maximum time of operation at low speed being exceeded (tLS).
• Reversal of the direction of correction (PIC):
If PIC = nO, the speed of the motor increases when the error is positive. An example application is pressure control with a compressor.
If PIC = YES, the speed of the motor decreases when the error is positive. An example application is temperature control with a cooling fan.

Manual–Automatic Operation with PI Regulator
This function combines PI regulator and switching of reference rFC (page 45). The speed reference is given by Fr2 or by the PI function, depending on the state of the logic input.
Setting up the PI Regulator 1. Configure the drive controller for PI regulator. See the diagram on page 62.
2. Perform a test with the factory configuration. In most cases, the factory settings are sufficient. To optimize the drive controller, gradually adjust rPG or rIG independently and observe the effect on PI feedback in relation to the reference.
3. If the factory settings are unstable or the reference is incorrect, perform a test with a speed reference in manual mode (without PI regulator) and with the drive controller on load for the speed range of the system:
— In steady state, the speed must remain stable at the reference, and the PI feedback signal must be stable.
— In transient state, the speed must follow the ramp then stabilize quickly, and the PI feedback must follow the speed.
If this is not the case, check the drive controller settings and the sensor signal and cabling.
4. Enable PI regulator.
5. Set brA to nO (no auto-adaptation of the ramp).
6. Set the speed ramps (ACC, dEC) to the minimum permitted by the application without triggering an ObF fault.
7. Set the integral gain (rIG) to the minimum value.
8. Observe the PI feedback and the reference.
9. Perform several RUN/STOP cycles, or vary the load or reference rapidly.
10. Set the proportional gain (rPG) to obtain the ideal compromise between response time and stability in transient phases (slight overshoot and 1 to 2 oscillations before stabilizing).
11. If the reference varies from the preset value in steady state, gradually increase the integral gain (rIG) and reduce the proportional gain (rPG) in the event of instability (pump applications) to find a compromise between response time and static precision. Refer to the figure onpage 62.
12. Perform in-production tests throughout the reference range.

The following are the recommended settings for brake control:
1. Brake release frequency (brL):
— Horizontal movement: Set to 0.
— Vertical movement: Set to the nominal slip of the motor in Hz.
2. Brake release current (Ibr):
— Horizontal movement: Set to 0.
— Vertical movement: Set to the nominal current of the motor at first, then adjust the release current to prevent jolting on start-up. Ensure that the maximum load is held when the brake is released.
3. Brake release time (brt):
— Adjust according to the type of brake. Brake release time is the time required for the mechanical brake to release.
4. Brake engage frequency (bEn)
— Set to twice the nominal slip of the motor, then adjust according to the result.
NOTE: The maximum value of bEn is LSP. Ensure that LSP is set to a sufficient value.
5. Brake engage time (bEt):
— Adjust according to the type of brake. This is the time required for the mechanical brake to engage.
6. Brake release pulse (bIP):
— Horizontal movement: Set to nO.
— Vertical movement: Set to YES and ensure that the motor torque direction for forward control corresponds to the upward direction of the load. If necessary, reverse two motor phases. This parameter generates motor torque in an upward direction, regardless of the direction of operation, to maintain the load while the brake is releasing.

DISPLAY MENU SUP-
The display menu parameters can be accessed with the drive controller running or stopped. This menu can be accessed with the access locking switch on the remote keypad display in any position.
Some functions have numerous parameters. To simplify programming and to keep parameter lists short, these functions have been grouped in sub-menus. Like menus, sub-menus are identified by a dash after their code. For example, LIA- is a submenu.
When the drive controller is running, the value of one of the display parameters is shown. To change the parameter displayed, scroll to the desired display parameter and press the ENT key. To retain your selection as the new default, press and hold the ENT key again for 2 seconds. The value of this parameter will be displayed during operation, even after power to the drive controller has been cycled. If the new choice is not confirmed by pressing the ENT key a second time, the drive controller will return to the previous parameter after power is cycled.

© 2004 Schneider Electric All Rights Reserved 85
SECTION 4: MAINTENANCE AND TROUBLESHOOTING
PRECAUTIONS Read the following safety statements before proceeding with any maintenance or troubleshooting procedures.
ROUTINE MAINTENANCE Perform the following steps at regular intervals:
• Check the condition and tightness of the connections.
• Make sure that the ventilation is effective and that the temperature around the drive controller remains at an acceptable level.
• Remove dust and debris from the drive controller, if necessary.
NORMAL DISPLAY A normal display with no fault present and no run command shows:
• The value of one of the display parameters (see page 82).
• init: Initialization sequence
• rdY: Drive ready
• dcb: DC injection braking in progress
• nSt: Freewheel stop. See page 15.
• FSt: Fast stop
• tUn: Auto-tuning in progress
FAULT DISPLAY If a problem arises during setup or operation, ensure that all ambient environment, mounting, and connection recommendations have been followed.
The first fault detected is stored and displayed, flashing, on the screen. The drive controller locks and the fault relay (RA-RC) contact opens, if it has been configured for this function.
Drive Controller Does Not Start, No Fault Displayed
If the drive controller will not start and there is no display indication, consider the following:
1. Check the power supply to the drive controller.
2. The assignment of the fast stop or freewheel stop functions prevents the drive controller from starting if the corresponding logic inputs are not powered up. In this case, the drive controller displays nSt in freewheel stop mode and FSt in fast mode. This is normal, since these functions are active at zero speed so that the drive controller will stop safely if there is a wire break.
3. Ensure that the run command inputs have been actuated in accordance with the chosen control mode (tCC parameter in the I-O- menu. See page 31).
DANGERHAZARDOUS VOLTAGE
• Disconnect all power before servicing the drive controller.
• Read and understand these procedure and the precaution on page 14 of this manual before servicing the ATV31 drive controllers.
• Installation, adjustment, and maintenance of these drive controllers must be performed by qualified personnel.
Failure to follow this instruction will result in death or serious injury.
Section 4: Maintenance and Troubleshooting VVDED303042USR6/04Fault Display 06/2004
© 2004 Schneider Electric All Rights Reserved86
4. If an input is assigned to the limit switch function and this input is at state 0, the drive controller can only be started by sending a command for the opposite direction (see page 74).
5. If the reference channel (page 39) or the control channel (page 40) is assigned to Modbus or CANopen, the drive controller displays nSt on power up and remains stopped until the communication bus sends a command.
Clearing Faults The drive controller can be unlocked after a fault by the following methods:
• Removing power from the drive controller until the display clears.
• Automatically, if the automatic restart function is enabled (parameter Atr is set to Yes, see page 77)
• By a logic input, if a logic input is assigned to the fault reset function (parameter rSF assigned to LI•, see page 77)
Faults Which Cannot Be Automatically Reset
Faults which cannot be automatically reset are listed in the table below. To clear these faults:
1. Remove power from the drive controller.
2. Wait for the display to go off completely.
3. Determine the cause of the fault and correct it.
4. Reapply power.
